The Steelers signed free agent wide receiver Jayson Foster on Friday. Foster was on both the Steelers and Denver Broncos practice squads during the 2008 season. Foster originally signed with the Miami Dolphins in 2008 as an undrafted rookie out of Georgia Southern. Foster joins a very deep receiver unit of the Steelers and will likely be a candidate once again for the practice squad with a great training camp. Foster is 5-7, 185lbs.
