Jacksonville Jaguars tight end Julius Thomas will undergo surgery on his injured finger Wednesday, reports NFL.com's Ian Rapoport.

Thomas could miss up to a month with the injury, reports Rapoport. ESPN's Adam Schefter reported Thomas was expecting to undergo surgery, but sought a second opinion Tuesday.

Thomas was injured during the Jaguars’ preseason opener against the Pittsburgh Steelers. Jacksonville signed Thomas, 27, to a five-year, $46 million deal in March.

Clay Harbor and Marcedes Lewis are the next two tight ends on the Jaguars’ depth chart.
