SAN DIEGO (AP) The San Diego Chargers selected J.J. Watt's younger brother, Wisconsin fullback Derek Watt, in the sixth round of the NFL draft on Saturday.

Watt will be reunited with Chargers running back Melvin Gordon, who had a miserable rookie season in large part because he didn't have a fullback to block for him and the line struggled to open holes.

J.J. Watt, the Houston Texans' star defensive end, is a three-time Associated Press Defensive Player of the Year.

Derek Watt was a four-year starter with the Badgers.

The Chargers also drafted Ohio State linebacker Joshua Perry in the fourth round, Akron outside linebacker Jatavis Brown in the fifth round and Texas A&M punter Drew Kaser in the sixth.

Perry is the second former Buckeyes player taken by the Chargers, who picked defensive end Joey Bosa with the third selection overall on Thursday night.

Perry has played both inside and outside linebacker.

He is expected to add depth to a unit that was ranked only 20th overall in the NFL and 27th against the run.

The Chargers, who finished 4-12 last year and winless in the AFC West, have four more picks Saturday.
