The 49ers said Thursday that they have signed six players to reserve/future contracts, a group that includes five players who ended the season on the practice squad.

The lone exception is guard Wayne Tribue (6-feet-3, 329 pounds), who spent time on the Broncos’ and Saints’ practice squads as a rookie last year.

The others signed were wide receiver Ricardo Lockette, guard Al Netter, offensive tackle Kenny Wiggins, linebacker Nate Stupar and defensive tackle Lamar Divens.

By signing a reserve/future deal, the six players will be under contract with the 49ers when the league year begins March 12. Safeties Curtis Taylor and Michael Thomas, who ended the season on the practice squad, were not signed to reserve/future deals. They can be signed by another team.

Williams thanked Commissioner Roger Goodell for reinstating him. “I take full responsibility and apologize for my previous actions. … I’m grateful for this opportunity.”
