ST. LOUIS (AP) -- Mark Clayton caught a career-best 10 passes after only three practices with the St. Louis Rams.
Clayton was rookie Sam Bradford's main target in a 17-13 opening loss to the Arizona Cardinals on Sunday. He credited a photographic memory for his ability to quickly learn a new playbook.
The Rams acquired Clayton last Monday from the Baltimore Ravens. He caught 10 passes for 119 yards, including a 39-yarder that was the team's longest of the day.
Clayton's previous high was eight receptions.
