stocks finished the day lower on wall street getting back the modest gains they made the day before. the dow fell 40 points, s&p lost nearly three and the

from colorado's sports leader here's rod mackey. >> let me clarify the name. they're the houston texans, not brock and the texans. it seems all anyone wants to talk about is the broncos qb turned texans qb. most were disappointed when osweiler left but not trevor siemian. after all, siemian would likely still be sitting on the bench had osweiler chosen to resign here. >> you know, i learned a ton learned a ton from brock as well and the situation that he was in. so brock is a good friend and i wish him really well. >> we talk time to time whether it's texts or whatever. obviously i think a lot of him, had a lot of nice battles with him on the football field last year. we won some big games. you never forget that. that's part of football. so yes, we got a lot of respect for each other i think. >> brock called kub after the ambulance incident to make sure

key player from the broncos opponent and in week the player was brock osweiler. mike klis was part of that conversation. he joins us live now from broncos headquarters. we get to finally catch up with the old qb, didn't we, mike? >> reporter: we did. i was impressed by how he handled all the questions that came his way. most of the questions went back to his decision to leave previous four years, had been developed by the coaching staff here. he was ready to become the heir apparent to peyton manning, take over the defending super bowl champs. instead he leave for houston where he thought he had a better chance to succeed and brock didn't dodge any questions. i thought he might say i've moved on, guys. that was then. i'm now a houston texan. he didn't do that. he explained all his decisions. two things of note. he did indicate that the

extending an offer. that was one and two, he also reconfirmed that he preferred the bill o'brien often which comes from the patriots which the broncos used in the adam gase peyton manning heyday versus the gary kubiak offense which is a little more run oriented. >> looking forward what do you expect to see from no. 17 on monday night, mike? >> reporter: i expect him to try to get rid of the ball quick just did last thursday, just like matt ryan did. that seem to be the blueprint. he'll try to hit his tight ends. i'm not sure he'll go as much to his receiver deandre hopkins like he likes to. they'll try to neutralize the pass rush, but i think the broncos have this game. it's hard for me to believe they're losing to brock and the texans on monday night. >> mike, it's the houston texans. it's not brock and the texans. i just clarified that.

and i disagree, not this week. it's brock and the texans. >> mike. thank you for talking about brock and the texans. finally we are all about the broncos here, but everywhere else everyone else seems to be focused on the cubs, even broncos running back kapri bibbs who actually flew back from chicago to watch one of their playoff games. >> i didn't really have a choice. now you got the cub games. she would take me to all i was seeing sammy sosa and i was like all right. this was the team my mom was a fan of. i'm a cubs fan. >> tonight it will be interesting to see what happens, john lester, the cubs' ace on the mound. it's funny, looking stuff up now. like 100 bucks you can go to the cubs game in l.a., triple

if it's cubs/indians, forget it. >> are you going with the sentimental favorite? >> i'm going cubs. >> i'm going dodgers because i'm not jinxing them. >> nbc nightly news is next. after that next with kyle clark at 6:00 and we'll all see you back here at 9:00 and 10:00. >> we hope to anyway.

tonight, refuse to lose. donald trump's defiant new message, doubling down on his refusal to say he'll accept the results of the election. >> i'll keep you in suspense. >> new fall-out from a nasty debate. >> no puppet. no puppet. you're the puppet. such a nasty woman. tunnels. richard engel inside the underground bunkers in iraq where isis fighters lived before they fled for their lives. hunt for a serial killer. chilling new 911 calls as police ask for help in an unsolved murder spree. who is the sniper targeting victims that include children? and crumbling nightmares. a billion dollar disaster for families watching their houses crack apart.
