The Boston Celtics have reportedly inked a new cable television deal that will give the NBA team an equity stake in Comcast SportsNet New England.

Besides a big increase in its annual rights fee the Celtics would get up to a 20% equity stake in the regional sports network. The increase in the rights fee, which is expected to be about $20 million a season, will be included in the league’s Basketball Related Income and therefore part of the salary cap. But none of the income the Celtics owners will get from their equity stake in the profitable RSN will be included in BRI and, by extension, player salaries.

The new deal will enrich its owners more than a comparable deal comprised entirely of a rights fee.
