WESTMINSTER, Md. — Baltimore Ravens wide receiver Derrick Mason has ended his retirement.

He joined the team Saturday at training camp after the morning practice session, and expects to be back on the field Sunday morning.

Mason announced his retirement on July 13, but acknowledged later he was having second thoughts. He called Ravens owner Steve Bisciotti on Saturday morning, expressing his decision to return. Mason is expected to send a letter to the NFL stating his intentions.

The 35-year-old played a key role in helping Baltimore reach the AFC championship game last season. He started all 16 games and led the Ravens in receptions (80) and yards receiving (1,037). He then added 12 catches for 190 yards and a touchdown in three playoff games.
