The New York Jets have reached an agreement in principle with San Francisco 49ers defensive coordinator Robert Saleh to become their head coach.

Saleh will become the Jets' 20th head coach, taking the helm after Adam Gase was fired earlier this month.

The 41-year-old joined the 49ers in 2017 after previous spells in the NFL with the Houston Texans, Seattle Seahawks and Jacksonville Jaguars.

The Jets confirmed on Thursday they had "agreed in principle" for Saleh to become head coach.

ESPN reported Saleh was expected to make 49ers passing game coordinator Mike LaFleur his offensive coordinator at the Jets.

Defensively, the 49ers ranked fifth for total yards allowed (5,030), seventh in rushing yards (1,703) and fourth in passing yards (3,327) in 2020.

The Jets, who last reached the playoffs in 2010, finished the 2020 season with a 2-14 record.
