Buffalo Bills WR Jordan Matthews, LB Ramon Humber out indefinitely with thumb injuries

Buffalo Bills wide receiver Jordan Matthews and linebacker Ramon Humber are both expected to undergo thumb surgery and will be out indefinitely, coach Sean McDermott announced Monday.

While McDermott did not elaborate on the length of either player's absence, NFL Network Insider Ian Rapoport reported Monday morning that Matthews is expected to miss about one month.

The surgery will be the second for Matthews since he was acquired from the Philadelphia Eagles for cornerback Ronald Darby on Aug. 11. Matthews had sternum surgery in the summer.

Matthews scored his first touchdown of the season in Sunday's 23-17 victory over the Atlanta Falcons. The 25-year-old has 10 receptions for 162 yards in four games for the Bills (3-1).

Rookie Zay Jones, fellow wide receiver Andre Holmes and tight end Charles Clay likely will see an increase in workload in the absence of Matthews.

Humber has recorded a team-leading 37 tackles in four games this season for Buffalo.

The 30-year-old Humber was replaced in Sunday's contest by rookie Matt Milano, a fifth-round pick out of Boston College.
