The Las Vegas Raiders brought in former San Francisco 49ers quarterback Colin Kaepernick for a workout on Wednesday, in hopes that he can help improve their depth at the position.

According to reports, Kaepernick’s arm strength and conditioning stood out, but no signing was imminent.

The Raiders considered Kaepernick’s work out a “positive,” a source said. Las Vegas could be looking for another passer to serve as the backup for Derek Carr despite trading for former New England Patriots quarterback Jarrett Stidham and signing Nick Mullens.

After the workout, head coach Josh McDaniels did not shed any insight on the team’s plans for Kaepernick, stating that he does not discuss players who are not currently on roster.

“Just by standard procedure, we will only talk about the people that are on our team,” McDaniels said. “[General manager] Dave [Ziegler] and his staff have worked out tons of guys this spring, and we really don’t make comments about the evaluations that we’ve made; or what they look like, what they didn’t look like.

“They’re kind of private for us as we look at things to try to make decisions to make the team better.”

Kaepernick, 34, hasn’t played in the NFL since 2016, the year he began protesting racial inequality during the national anthem. The only other team known to have brought him in for a visit since then was the Seattle Seahawks in May 2017.

“If there’s an opportunity to improve the team, we’ve said it from Day 1 that we would look at every opportunity,” McDaniels said when asked about Kaepernick’s workout. “He’s not the first player that we’ve looked at, and not the last one. There’s going to be a lot of people that are going to come in and out of this building. … The evaluations we make are private for us, and if we make a decision to add someone to the team then we’ll do it.”
