Jonathan Martin’s representatives have notified the Miami Dolphins about allegations of player misconduct within the locker room, spurring the team to ask the NFL to launch an independent inquiry Sunday, and then announcing the indefinite suspension of offensive lineman Richie Incognito.

“We are taking these allegations very seriously and plan to review the matter further,” the Dolphins said. “. . . As an organization, we are committed to a culture of team-first accountability and respect for one another.”

The announcements came late on a busy Sunday, in which new details of the alleged abuse suffered by Martin came to light, and in which a potential new controversy was just beginning.

The latest twist:

Young Dolphins players are under pressure to dig deep into their pockets to pay for veterans’ social outings, a practice that is straining their finances and locker room chemistry, according to a source with direct knowledge of the situation.

These allegations come on the heels of an ESPN report Sunday morning that Incognito pressured Martin into paying $15,000 for an unofficial team vacation to Las Vegas — a trip that Martin, an offensive tackle, didn’t even join.

The Dolphins said Sunday night they suspended Incognito indefinitely for conduct detrimental to the team.

According to a statement from the team, “We believe in maintaining a culture of respect for one another, and as a result we believe this is in the best interests of the organization at this time.”

One young defensive player, whose privacy the Miami Herald is protecting, is on his way to going broke because he has been unable to say no to the older players, a source said.

“Everything tastes better when rookies pay for it,” veteran defensive end Jared Odrick wrote on Twitter over the weekend. “Yes, the bill would make you sick.”

Younger players were handed the tab for a $30,000 team dinner, according to a source. The rookie minimum salary this year is about $400,000.

Will Davis, a rookie cornerback, tweeted Sunday: “The bill was definitely split. . . . They would never put that on one man to pay for it all. Haha now that would be crazy . . .”

Every team has a rookie dinner outing, which is what Odrick was referring to in his tweet, but at issue are incidents that extend far beyond a onetime meal deal.

The source characterized Dolphins veterans using younger players as ATMs to finance their nightlife whims. These older players have been caught up in the fast-paced Miami lifestyle without the burden of having to pay for it, the source continued.
