Former Alabama All-American Reggie Ragland finally made his NFL debut on Monday night - 521 days after he was drafted.

Ragland started at right inside linebacker for the Kansas City Chiefs against the Washington Redskins on Monday night.

After the Buffalo Bills selected Ragland with the 41st choice of the 2016 NFL Draft, he suffered a season-ending knee injury at training camp on Aug. 5, 2016.

When the Bills drafted Ragland, he was slated to start at one of their inside-linebacker positions. But while he was recovering from a torn anterior cruciate ligament, Buffalo changed coaches -- firing Rex Ryan and hiring Carolina Panthers defensive coordinator Sean McDermott. The change in coaches brought a change in defensive scheme and eliminated the position that Ragland was brought in to play.

In McDermott's defense, Ragland was competing with Preston Brown for the middle-linebacker spot instead of playing beside him as the Bills' inside linebackers, as was originally intended under Ryan. Brown made 135 tackles for Buffalo in 2016 after making 109 and 117 in his first two seasons in the NFL.

The Bills traded Ragland to the Chiefs for a fourth-round pick in the 2019 NFL Draft on Aug. 28.

Ragland played in three preseason games with the Bills in August, but he was inactive for Kansas City's first two regular-season games. Ragland was active for last week's game against the Los Angeles Chargers, but he did not play.

The Chiefs used Derrick Johnson and Ramik Wilson as their starting inside linebackers during the first three games of the 2017 season.

In his 13th season with Kansas City, Johnson has four Pro Bowl invitations and enjoyed an All-Pro season in 2011.

Entering his third season out of Georgia, Wilson became a starter last year for the Chiefs. Wilson was on the Kansas City practice squad in 2016 when injuries to Josh Mauga and Justin March put him in the lineup. He started the Chiefs' final 11 games.

Ragland started with Johnson on Monday night.
