Bills sign rookie free-agent DB Unamba

The Buffalo Bills have signed rookie free agent defensive back
Don Unamba.

The signing was announced Wednesday, after the Bills completed
their fourth day of training camp in suburban Rochester.

Listed at 6-foot-1 and 192 pounds, Unamba initially signed with
St. Louis following the NFL draft before being cut by the Rams in
June. He played college at Southern Arkansas, where he had three
interceptions and a school-record 17 pass breakups in 11 starts
last season.

The Bills return to practice on Friday.
