COSTA MESA, Calif. -- The Los Angeles Chargers did their homework on Cardale Jones before the 2016 draft, with quarterbacks coach Shane Steichen traveling to Ohio State to hold a private workout with the quarterback prior to draft day.
Chargers general manager Tom Telesco also had scouts present at Jones' pro day.
The Chargers received Jones in a trade with the Buffalo Bills this week for a conditional seventh-round pick. Jones joins a quarterback room for the Chargers that includes franchise quarterback Philip Rivers, backup Kellen Clemens and former Arizona State quarterback Mike Bercovici.
The Chargers waived undrafted rookie quarterback Eli Jenkins to make room for Jones on the 90-man roster. Jones will wear No. 5 on the field when the Chargers begin training camp at Jack Hammett Sports Complex on Sunday.
Telesco said the Chargers had been discussing a potential trade for Jones with the Bills since the draft, but finally executed the deal this week.
A fourth-round selection by the Bills, the former Ohio State quarterback worked with Chargers head coach Anthony Lynn last season while the latter served as Buffalo's offensive coordinator.
For now, Telesco said the only expectation for Jones is to come in and compete.
"Obviously we're looking for competition at that spot," Telesco said. "And with Cardale, he's a quarterback with some developmental traits that are hard to find.
"Our scouts had really high grades on him when he came out in the draft. And then the fact that Anthony had him in Buffalo for a year -- that way he knew him -- so it was a good blend for us and a good combination for that. Since Brad Sorensen, we haven't had a young quarterback in our system that we could work with, so he's going to be one of those guys."
Jones trained in San Diego before the draft last year with quarterback guru George Whitfield, working alongside Rivers' brother, Stephen Rivers.
"He's big. He's strong. He's got a strong arm," Telesco said of Jones. "He's a pretty good athlete, played at a high level and played well. But his body of work in college is not as large as you would like, so we know it's going to take some time. But it's hard to find a quarterback with those type of skills."
