The Washington Redskins signed defensive end Matt Ioannidis to a three-year extension with a base value of $21.75 million on Thursday, according to a source. He can earn another $3 million in incentives. The 25-year-old former fifth-round pick has flown under the radar the last two years and has 12 sacks in that time, including 7.5 quarterback takedowns in 14 games in 2018.
