49ers do extra homework on Oregon tackle Tyrell Crosby

The 49ers last week conducted a workout with Oregon offensive tackle Tyrell Crosby, one of several offensive linemen they are looking into in the run-up in the draft.

According to Pro Football Focus, Crosby didn't allow a sack or even a quarterback hurry while playing left tackle for the Ducks in 2017. Some teams see the 6-foot-5, 325-pound Crosby as a right tackle in the NFL, other teams reportedly are looking at him as a guard. Crosby has said he'd be happy to play either, although he only played tackle at Oregon.

"Every team I’ve talked to has asked me if I’ve played right tackle," Crosby said at the scouting combine. "And I told them freshman sophomore year I was right tackle, junior senior year I was left. (The difference is) everything’s just like a mirrored version of it, really. People think it’s just pretty easy to switch over, but you learn all same footwork but different feet."

The 49ers have needs at a number of spots on the offensive line. Their starting right tackle, Trent Brown, is recovering from shoulder surgery and is not signed beyond the 2018 season. Left tackle Joe Staley turns 34 years old this year and is signed for another two seasons.

At guard, the 49ers have Laken Tomlinson penciled in on the left side. Like Brown, however, Tomlinson is heading into the final year on his contract. Jonathan Cooper and Joshua Garnett – neither of whom has distinguished himself in the NFL – are among those competing to start at right guard.

Crosby has good athleticism for a man his size, which likely is what intrigues the 49ers. He's expected to be taken somewhere in the second round of next week's draft.

Crosby's workout occurred in his home town of Las Vegas, per a league source. They also met with him last month at the NFL scouting combine.

The team also has worked out UCLA offensive linemen Kolton Miller (Roseville High) and Scott Quessenberry, Nevada offensive lineman Austin Corbett, SMU prospects Evan Brown and Mason Gentry and Wesley guard Matthew Gono.

They have had official visits with Iowa center James Daniels and offensive tackle Brian O'Neil of Pittsburgh.
