That’s one down for the Rangers.

On the eve of the beginning of training camp Thursday, the Blueshirts agreed to terms with restricted free agent forward Brendan Lemieux to a one-year deal, the team announced.

The deal is for $925,000, according to The Post’s Larry Brooks. The gritty 23-year-old forward had a one-year qualifying offer of $874,125 this summer.

The Rangers still have to get defenseman Tony DeAngelo under contract, though the team doesn’t have much cap room to negotiate with the 23-year-old blueliner, who could become the team’s first camp holdout since Derek Stepan in 2013.
