Profootballtalk.com is reporting that running back Darius Walker has signed with the Denver Broncos, according to agent Drew Rosenhaus’ Twitter feed.

The 23-year-old was signed as an undrafted free agent in 2007 by the Houston Texans.

Though undersized, he’s considered a between-the-tackles runner with good hands, yet a little slower than a true feature back.

With limited action in 2007, Walker carried the ball 58 times for 264 yards and one touchdown for a 4.5 YPC average.
