The Cleveland Browns cleared out a little more salary cap space by releasing veteran defensive end Adrian Clayborn after one season. Clayborn appeared in 15 games for the Browns last season after signing a two-year, $5.75 million contract as a free agent in March. The 32-year-old had 3 1/2 sacks, 12 tackles and forced a fumble while in Cleveland’s defensive line rotation. The team will save $3 million under the cap with Clayborn off the books. Clayborn spent three seasons with the Atlanta Falcons and four in Tampa Bay before signing with the Browns.
