Bills add WR depth by signing Kerley

The Bills added depth to the wide receiver group and defensive line with the signings of veterans WR Jeremy Kerley and DT Tenny Palepoi on Monday.

Kerley rejoins the AFC East after making two different stints with the New York Jets, who selected him with a fifth-round pick in the 2011 NFL Draft. Both players signed one-year contracts.

Kerley served a four-game NFL suspension last season for violating the league's policy on performance-enhancing drugs. He registered a career-high 64 receptions to go along with 667 yards and three touchdowns in San Francisco.

Kerley will have an opportunity to contend for a backup spot behind Kelvin Benjamin and Zay Jones.

He led the Jets in receptions and receiving yards in 2012 and 2013 working a good deal out of the slot before his role was reduced under the club's new coaching staff.

Palepoi, 27, registered 24 tackles for the Los Angeles Chargers last season, earning a below-average grade of 60.0 from PFF. He spent the past four seasons with the team as a rotational defensive tackle.

The Bills on Monday also announced re-signing four exclusive rights free agents, including defensive end Eddie Yarbrough, who started six games previous year.

Palepoi already has a former college teammate on the roster in Lotulelei.
