The 49ers are “believed” to be one of the NFL teams with interest in pending free agent tight end Trey Burton, according to Matt Barrows of the Sacramento Bee.

Half the league reportedly has interest in Burton, so the 49ers will certainly have competition if they seek to sign the 26-year-old former undrafted free agent. But San Francisco will enter the free agent period with roughly $66MM in cap space (good for fifth in the league), so the club will have the funds needed to make a real pursuit of Burton, who remains unlikely to re-sign with the Eagles after rejecting an offer from Philadelphia that he did not consider “serious.”
