Orchard Park, NY (SportsNetwork.com) - The Buffalo Bills have signed Miami Dolphins tight end Charles Clay to an offer sheet.
Miami placed the transition tag on Clay earlier this month, allowing him to field offers from other teams. The Dolphins now have five days to match.
Terms of the offer weren't disclosed by the Bills, but NFL.com reported the contract to be worth $38 million over five years, including $24.5 million over the first two years. Under the transition tag, Clay would have earned just $7.7 million in 2015 with the Dolphins, although Miami was reportedly trying to work out a long-term deal.
Clay has played his entire four-year career with the Dolphins, making the transition from fullback in college to tight end. He caught 58 passes for 605 yards and three touchdowns last season after hauling in a career-best 69 passes for 759 yards with six scores in 2013.
In 58 games, 47 of which have been starts, the Tulsa product has 161 receptions for 1,809 yards with 14 touchdowns.
The Dolphins have already added a tight end through free agency, signing Jordan Cameron to a two-year deal.
