Thursday was a good day for Earl Thomas.

"Today is a good day," were Thomas' words to open his weekly session with Seattle-area media. "It's my daughter's birthday, just to let you all know. So happy birthday to my daughter."

Thomas' daughter, Kaleigh Rose, was born three years ago today. She came into this world just minutes before the Seahawks kicked off against the Green Bay Packers on Monday Night Football at CenturyLink Field, a game Seattle won with a Hail Mary toss from quarterback Russell Wilson to wide receiver Golden Tate on the final play of the game. Thomas rushed to the hospital after the win to see his new baby girl.

"Yup, when the magic happened," Thomas said. "Golden Tate's catch, my daughter's here on Earth."

Wednesday was another good day for the free safety, as he and his Seahawks teammates welcomed Kam Chancellor back to the Seattle locker room. The two players who share the same draft class (2010) were back on the practice field together for the first time since before the start of training camp, which along with the first two regular-season games, Chancellor chose not to attend.

"He looked smooth," Thomas said of Chancellor. "The first day he just fit right in. He really understands what's going on around him. He helps in getting people lined up. He's a great communicator. He's going to be a big help."

At the strong safety position in Chancellor's absence, Thomas worked alongside second-year pro Dion Bailey in Week 1 against the St. Louis Rams and fourth-year pro DeShawn Shead in Week 2 against the Packers. For the most part, both players played well in Chancellor's place, but it's admittedly hard to sub for everything Chancellor brings as the physical enforcer on the back-end of Seattle's defense. Plus there's the fact that Thomas and Chancellor have spent the past four years starting side-by-side, developing into one of the NFL's best safety duos. So how does No. 31's return personally affect No. 29?

"I just trust him," Thomas said. "I trust him."

Outside of a few dropped balls at Wednesday's workout, Thomas said he doesn't see any reason why Chancellor wouldn't be able to play in this Sunday's home-opener against the Chicago Bears.

"No, he looked great," Thomas said. "He just had butterfingers on a couple of missed interceptions. He's a great athlete. He's trimmed down and he looks ready to go."
