Undrafted rookie wide receiver Danario Alexander will sign with the St. Louis Rams, Jason La Canfora of the NFL Network reports.

Alexander (6-5, 221) caught 191 passes for 2,778 yards and 22 touchdowns during his four-year career at the University of Missouri. Knee injuries limited his playing time until his senior season, when the first-time starter caught 113 passes for NCAA-best 1,781 yards with 13 touchdowns.

Alexander earned first-team All-Big 12 honors after the season, and displayed a 43" vertical leap and 11'01" broad jump at the Senior Bowl. Unfortunately, he injured his left knee, requiring another surgery that prevented an NFL team from taking a flier on him in April.

Cleared to return to the field, Alexander hosted a "pro day" in Houston in late July, and worked out privately for the Rams and Seattle Seahawks. Alexander worked out again for the Rams on Sunday, and it's resulted in a contract.
