HENDERSON, Nev. — Las Vegas Raiders quarter Jimmy Garoppolo underwent surgery on his injured left foot after signing a free agent contract with the team in March, a league source confirmed to ESPN on Thursday.

“Everything is going well,” the source said.

Garoppolo signed a three-year, $72.75 million contract with Las Vegas on March 17, although his first meeting was delayed a day.

“He’s going through his process as we know he will,” Raiders coach Josh McDaniels said. “Nothing has happened that would surprise us based on what we had.”

McDaniels would not say whether Garoppolo had committed to the procedure, which was first reported by The Athletic.

McDaniels said only that there were no surprises and that the QB will not be on the field for the start of OTA practices. He agreed that Garoppolo could be out until the start of training camp.

Garoppolo was injured in Week 13 by a San Francisco 49ers the season ended and he never came back.

First round pick Tyree WilsonThe Texas Tech edge rusher, who was taken seventh overall in the draft last month, was also out, rehabilitating his surgically repaired right foot, which was injured on Nov. 12.

“We know we’re not going to play more than 100 days, so they’re doing everything they can to get better,” McDaniels said. “And when they’re all ready to go, then eventually they’ll be back on the field.

Some of them may be ready before spring is over; some of them won’t. And we always err this time of year on being smart…. out there in May, that’s a bad decision. … He’s in all the meetings — all the football things he can do that don’t jeopardize anybody’s ability to be ready to go here this season. “
