The Texans placed the franchise tag on Clowney in March. Barshop noted the two sides have until July 15 to negotiate a long-term extension; otherwise he'll play on a one-year tender.
Clowney will earn a little over $15.9 million in 2019 if he doesn't sign an extension. According to the Houston Chronicle's John McClain, Clowney doesn't plan a Le'Veon Bell-type holdout in the absence of a new contract; he'd suit up under the franchise tag and return to the negotiating table at a later date.
While acknowledging he's unsure when the three-time Pro Bowler will arrive for the team's offseason training, head coach Bill O'Brien downplayed the situation, per NFL Network's James Palmer:

Bill O’Brien told reporters today he doesn’t know when Jadeveon Clowney will show up and added “It’s up to him”. But also said he believes that Clowney is working out on his own and will be ready for when he shows up. Clowney was tagged by the Texans and would like a new contract
Clowney also missed the Texans' OTAs in 2018, and it didn't impact his performance on the field. The 26-year-old finished with 47 combined tackles and nine sacks. Pro Football Focus ranked him as the 46th-best player during the 2018 season.
Houston has two more rounds of OTAs, running from May 28-30 and June 3-4. The team's mandatory minicamp begins June 11, which is seemingly the most logical date for Clowney's return.
