CLEVELAND — David Veikune went from outside linebacker to outsider with the Browns.

The team waived the disappointing second-round draft pick Tuesday, cutting ties with the former Hawaii defensive end that Cleveland tried to convert into a linebacker for its 3-4 system. The Browns used the No. 52 overall pick in last year’s draft to select Veikune (VAY-coo-nay), a 6-foot-2, 257-pounder.

But after playing in just 10 games last season, he showed little progress during training camp and the exhibition season this summer, and was let go as Browns coach Eric Mangini and general manager Tom Heckert trimmed one of the 12 linebackers still on Cleveland’s roster.

In addition to releasing Veikune, a member of the Browns’ outstanding kick-return unit last season, the team also claimed offensive lineman Steve Vallos (VAL-ose) off waivers from Seattle and signed defensive back Derrick Roberson.

Vallos played in all 16 games the past two seasons with the Seahawks, where he was with Browns president Mike Holmgren. Vallos can play center or guard.

The Browns released backup Billy Yates to make room for Vallos, whose 48 starts at Wake Forest are a school record.

Roberson played in six games for Tampa Bay last season. He was waived by the Buccaneers, Cleveland’s season-opening opponent this Sunday, last weekend.

The 5-foot-10, 180-pounder has also spent time on practice squads with Houston and Minnesota. He made 19 starts at Rutgers before signing as an undrafted free agent with Houston in 2007.
