Steve Smith Sr. Retires: Latest Comments and Reaction

Free-agent veteran wide receiver Steve Smith Sr. confirmed his retirement after the Baltimore Ravens' loss to the Cincinnati Bengals in Week 17, likely meaning an end to his 16-year career.

NFL on CBS shared Smith's postgame comments:

Smith also posted on his Twitter account regarding his decision to walk away from football:

On Friday, Smith posted his official retirement letter to the NFL:

Smith had announced Dec. 28 that he would "probably" retire after the final game of the regular season, according to Jamison Hensley of ESPN.com, ending his career after 16 NFL seasons.

Smith spent the last three years with the Ravens, continuing his reign as one of the best receivers in the game.

The five-time Pro Bowler did have to battle through injuries in the process, though, missing nine games in 2015 with a torn Achilles. It looked like an unceremonious ending to his career considering he had announced before that season he was going to call it quits.

But playing in just seven games fueled him to return, as he announced he would be back in Baltimore come 2016:

He finished the final year of his three-year contract with 70 catches, 799 yards and five touchdowns.

As one of the most tenacious competitors the game has ever seen, Smith continued to excel as one of Joe Flacco's go-to guys despite being 37 years old, via the NFL:

Smith made his name with the Carolina Panthers, posting seven 1,000-plus-yard seasons in 13 years with the organization.

His name is all over Carolina's record books, and he boasts Hall of Fame-level numbers:

Panthers Stats	Amount	Franchise Rank	Career Amount	NFL Rank (All-Time)
Receptions	836	1st	1,028	13th
Yards	12,197	1st	14,697	7th
TD	67	1st	81	27th

He played a big part in the Panthers winning the NFC title in 2003, when they fell just short to the New England Patriots in Super Bowl XXXVIII.

It will be the one glaring absence on his career resume, as Smith will ride off into the sunset without a championship.

However, that should do little to take away from the stellar career he built for 16 years.
