Matt Flynn will start at quarterback for the Seahawks' preseason opener at home against Tennessee on Saturday, and likely play the entire first half.

Flynn, signed as a free agent from Green Bay over the offseason and believed to have the inside track to the starting job, is competing with incumbent Tarvaris Jackson and rookie Russell Wilson in training camp.

That Flynn is getting the call to open the preseason over Jackson is an indication the coaching staff is pleased with his ability to pick up the playbook and command the offense. Flynn will take over the first-team reps in practice beginning Wednesday in preparation for the Titans.

"Matt has done a fantastic job so far," coach Pete Carroll said. "He's learned the system. He's on it. He can make all the adjustments, all the calls. He sees the defense really well. I love that he's moving well in the pocket. All of the things we're asking him to do he's fit that together so far.

"Now I need to see him in a situation where now he takes over and see what that looks like."

However, starting the preseason opener doesn't mean Flynn will necessarily start the regular-season opener next month.

"This is how we had planned it all along," Carroll said. "It's turned out that it's going to fit together and then we'll see how we go at the end of the week."

--Wide receiver Terrell Owens officially signed with the Seahawks on Tuesday, Carroll confirmed. It's a one-year, $1 million deal, according to ESPN.

Carroll tweeted Monday night: "@terrellowens welcome to the land of the #12thMan Terrell, see you in the morning... 8am meetings!!"
