Oakland Raiders sign wide receiver Michael Crabtree

The Oakland Raiders have confirmed that they have signed free agent wide receiver Michael Crabtree.

The 27-year-old was allowed to leave the San Francisco 49ers at the end of the 2014 season after an underwhelming campaign for the NFC West side.

After spending a month on the open market, which included visits to the Miami Dolphins and the Baltimore Ravens, Crabtree penned a one-year contract worth $5m (£3.3m) with the Raiders in an attempt to reignite his career.

Crabtree has recorded 347 receptions for 4,327 yards and 26 touchdowns in his six years in the NFL.
