MANAMA (Reuters) - Formula One has agreed to accept two new teams, including a US entry proposed by Nascar team owner Gene Haas, commercial supremo Bernie Ecclestone said on Sunday.

"They will be accepted," the Briton told reporters at the Bahrain Grand Prix when asked about Haas's application.

"We've also accepted another team as well. Whether they'll make it or not is another story. We are happy to have another couple of teams.

"I've spoken to (International Automobile Federation president) Jean Todt and we agreed yesterday that another two teams want to come in, we'll let them in," said the 83-year-old billionaire.

Last December, the FIA called for expressions of interest from potential new entries wanting to compete from 2015 or 2016, and set a January deadline. There are currently 11 teams competing.

Full applications had to be submitted by Feb 10 and a decision was supposed to have been taken by Feb 28, although the governing body has remained silent on the subject.

Haas, co-owner of the Stewart-Haas Nascar team, acknowledged in January that Haas Racing Development had responded to the FIA's call.

Former F1 principal Colin Kolles, who most recently led the failed Spanish HRT team after stints at Force India and its previous incarnations Jordan, Midland and Spyker, has also reportedly submitted a Romanian-backed application.
