Matthews has been sidelined with an undisclosed injury, but Titans beat reporter Paul Kuharsky, citing sources, wrote on Thursday that Matthews has been rehabbing from surgery for a torn meniscus.
Tennessee linebacker Derrick Morgan also suffered a meniscus injury in Saturday’s preseason game against Tampa Bay and also underwent a surgical procedure, according to Kuharsky. A source with knowledge of the injury said the injury could sideline Morgan for four to five weeks.
Matthews, who signed a one-year contract extension on Tuesday, reportedly underwent surgery during the first week of August.
“It’s good to see him working and kind of being excited about getting close to coming back and rejoining the team off PUP,” Titans coach Mike Vrabel said of Matthews.
The 28-year-old Matthews recorded 53 receptions for 795 yards and four touchdowns in 14 games last season, his second with the Titans. He posted career highs in catches (65), yards (945) and touchdowns (nine) in 2016.
Matthews collected 225 receptions for 3,136 yards and 21 scores in 79 career contests since being selected by the Miami Dolphins in the seventh round of the 2012 NFL Draft.
Morgan, a first-round draft pick of Tennessee in 2010, registered 7.5 sacks in 14 games last season after notching a career-high 9.0 in 2016.
