Cowing (hip) was a full participant in Saturday's practice, Jennifer Lee Chan of NBC Sports Bay Area reports.
Cowing suffered a hip injury sometime around last Wednesday's training camp session and has been absent from team activities since. The wide receiver's return to health will give him a chance to compete in next Thursday's preseason showdown with the Chargers. Cowing is currently listed as the starting punt returner for the team, but the 25-year-old will likely need to once again show he is a capable option at receiver to make the 53-man roster.
