LAS VEGAS — The World Series of Poker and ESPN are extending their deal to televise poker’s richest tournament through 2017.

The cable network and private casino operator Harrah’s Entertainment, Inc., which owns the series, were expected to formally announce the deal Tuesday.
The new seven-year deal begins in 2011, after the current deal expires. Financial terms were not disclosed.
ESPN, which produced 32 hours of programming from the series this year, is expected to devote at least that much time in future years under the new contract.
The network is scheduled to begin its coverage of this year’s $10,000 buy-in no-limit Texas Hold ’em main event on Tuesday.
The start of the tournament was held in July in Las Vegas, and is expected to finish in November.
