Two NFL teams filled head-coaching vacancies Wednesday, with the Cleveland Browns hiring Bengals offensive coordinator Hue Jackson and the New York Giants set to promote offensive coordinator Ben McAdoo.

Jackson, 50, finalized his deal on Wednesday, swiftly ending the Browns' search which began on Jan. 3 when owner Jimmy Haslam fired Mike Pettine after two losing seasons.

Jackson, who was the Oakland Raiders' head coach in 2011, also interviewed with the San Francisco 49ers.

The Browns likely were to part ways with troubled quarterback Johnny Manziel this offseason no matter who became their new coach, but Jackson securing the job is expected be the final nail in the coffin.

Jackson acknowledged during his introductory news conference Wednesday night that Manziel was a topic of conversation in his interviews with the organization.

According to multiple reports by national outlets, Jackson made it clear in those interviews that he would want to move on from Manziel if hired by the Browns.

Cleveland owns the No.2 overall pick in this year's draft and likely will use it on a quarterback — possibly California's Jared Goff or Memphis' Paxton Lynch.

•As for McAdoo and the Giants, multiple sources told New York's Newsday that the team is expected to make an official announcement Thursday morning. The two sides were working on finalizing a deal Wednesday night.

McAdoo, 38, also interviewed for the Eagles job, and their interest in him might have pushed the Giants toward making a decision when they did. McAdoo, according to a source, "wanted the New York job from the beginning."

Etc.

•The 49ers' coaching search circled back on a familiar candidate: Mike Shanahan.

Shanahan, the 49ers' offensive coordinator when they last won a Super Bowl 21 years ago, is "strongly back in the mix," ESPN reported.

•A person familiar close to the situation told the Associated Press that Lions defensive coordinator Teryl Austin has an interview with Tennessee on Friday for the Titans' head-coaching job. Former Vikings tight end Mike Mularkey, who went 2-7 as Titans interim head coach, reportedly will interview to keep the job Thursday.

•Seahawks running back Marshawn Lynch was listed as a full participant in the team's practice, and according to offensive coordinator Darrell Bevell had "probably one of the best days that he's had out here today" since returning from abdominal surgery.

Dan Campbell, who served as Dolphins interim head coach this season, is joining the Saints to become assistant head coach/tight ends coach.
