Swearinger said earlier in the day that he's no longer with Houston, but Texans head coach Bill O'Brien told the Houston Chronicle later on Monday that he was still on the team's roster.
The safety wrote the following in a post on Instagram: "One heck of an opportunity #texannation I appreciate everything and the opportunity and memories!! It's time for a new chapter and the defining moment of my career!! So long #HOUSTONTEXANS."
When O'Brien was asked to go into details about Swearinger's comments, he said "It's a free country."
John McClain of the Houston Chronicle noted that there had been rumors that Swearinger would be traded since before the draft.
Swearinger, 23, has played two seasons with the Texans since being selected in the second round of the 2013 draft.
He started 12 games at strong safety recording 74 total tackles, three forced fumbles and two interceptions last season for the Texans, who finished 9-7 and missed the playoffs for the second straight year.
Swearinger is due $722,391 in base salary this season.
