According to the report, the 26-year-old striker is one of a number of players being looked at by Rovers manager Tony Mowbray.
Antonsson joined Championship club Leeds from Swedish side Kalmar FF in the summer of 2016 for a transfer fee reported by The Lancashire Telegraph to be in the region of £2 million.
The 26-year-old arrived at Elland Road with a strong reputation, but the striker failed to make a massive impact at the Whites last season.
The Swedish striker was able to make only six starts in the Championship during the 2016-17 campaign, scoring just one goal in the process.
Joining Rovers on a season-long loan deal this summer would be a good move for Leeds striker Antonsson.
