It was not such a great day for Tannehill. (AP)

The Dolphins entered Sunday’s game against the Titans having won three of their last four and with Ryan Tannehill playing as well lately as any rookie quarterback not named Andrew Luck. And then the Titans touched down in Miami, and all hell broke loose.

In a shocking development, Tennessee dominated the Dolphins 37-3 -- it was the team’s worst home loss since 1968 -- and Tannehill played like a rookie quarterback who didn’t really know what he was doing. He wasn’t helped by a running game that was virtually non-existent (after an early Reggie Bush fumble, coach Joe Philbin yanked him from the game), meaning it was all on Tannehill.

For the first time since Week 4 on Sept. 30, Tannehill (23 of 39 for 217 yards) threw an interception. Not just one, mind you, but three picks that helped seal his team’s doom. This wasn’t all on Tannehill, obviously, but this was a tremendous disappointment for the entire franchise and for its quarterback. Grade: D.

Nick Foles, Eagles QB: Some in the Eagles fanbase have been clamoring for Foles to replace Michael Vick, on the strength of a strong preseason from the third-round draft pick. On Sunday, those fans got their wish when Vick had to leave the game in the second quarter with a concussion. Down by three points to Dallas, Foles heaved a 44-yard touchdown catch to a wide-open Jeremy Maclin in the third quarter for a 14-10 lead, but after that Philadelphia fell apart. The special teams allowed Dwayne Harris a 78-yard punt return score, and on the next drive, Brandon Carr intercepted Foles and ran it back for a touchdown. Later, he fumbled the ball in the end zone and Dallas recovered for its last score of the game. It wasn’t a horrendous debut by Foles -- who went 22 for 32 for 219 yards, a touchdown and an interception -- but it also wasn’t great. Grade: C-

Russell Wilson, Seahawks QB: He started off shaky and made some bad first-half decisions, but Wilson, like he always does at home, walked away with the victory, completing 12 of 19 passes for 188 yards and two touchdowns (with one lost fumble). Unlike many of the other rookie quarterbacks' teams, the Seahawks don’t need Wilson to be a hero. So he doesn’t usually play like one. But for the most part, he also plays solidly enough to help his team win. Grade: B

Some other notable performances:

Jarius Wright, Vikings WR: Without the services of Percy Harvin, Wright was active for the first time in his career and made the most of his chance, grabbing a 59-yard pass on the team’s first drive and then catching a 3-yard touchdown pass to give Minnesota a 7-0 lead. He finished with three catches for 65 yards.

Corey White, Saints CB: Helping New Orleans knock off the previously undefeated Falcons, White made a brilliant diving interception early in the second half. Good time to grab the first interception of his career.

Mohamed Sanu, Bengals WR: You might remember Sanu’s first career score when, on the first play of the Week 3 game versus the Redskins, he took the direct snap and threw a 73-yard touchdown pass. On Sunday, though, he was on the other end of the pass, grabbing a 10-yard toss from Andy Dalton. Sanu entered the game with five catches for 56 yards. On Sunday, he recorded four for 47.

Leonard Johnson, Buccaneers CB: A pick-six of Chargers quarterback Philip Rivers had to be awfully exciting for Johnson -- he high-stepped it the last 20 yards into the end zone, so I’m pretty sure he was pumped -- especially since it was his second interception in the past two weeks. At this point, Johnson is making a strong case for more playing time.

Janoris Jenkins, Rams CB: Not good

Chris Givens, Rams WR: Not good, Part II

Bruce Irvin, Seahawks DE: In Weeks 3-5, Irvin totaled four sacks, but since then we haven’t heard much from the No. 15 overall pick. Until Sunday when he recorded two of his team’s three sacks.
