Australian rugby star Jarryd Hayne could sign a futures contract with the Lions at the end of the regular season, according to a report in the Daily Telegraph.
The Lions and Chargers are considered the front-runners for Hayne's services.
When asked by the Daily Telegraph which team he will sign with, Hayne said, "You will find out in the due course."
NFL teams use futures contracts to secure players for the following season.
The Lions hosted Hayne, 26, on a visit last week. He is back in Australia while issues with his visa are resolved.
"We take a look at a lot of different people all the time," coach Jim Caldwell said after Hayne's visit. "It's a constant sort of exploration for us. We're always trying to look to find ways to improve, and we're looking at every option that's out there available to us."
If Hayne (6-2, 220 pounds) does transition to football, he'd likely be a running back / special teams player.
The Lions' interest in Hayne was sparked by running back Reggie Bush, who met Hayne during a promotional trip to Australia over the summer.
"He actually looks like an NFL running back," Bush said then about Hayne. "Looks like he could come play with us tomorrow. He's fast, strong. I like this guy."
