ENGLEWOOD, Colo. --
The team placed rookie offensive tackle Connor Rains on the waived/injured list to make room. Rains injured his foot during Friday's practice.
The 6-foot-5, 291-pound Sweeton had a brief stint with the Chiefs in May, signing with them as a college free agent May 11 before being released May 19.
Sweeton started 45 games in four seasons at Tennessee-Martin. He was a first-team Ohio Valley Conference selection as a senior last year.
